The present invention relates to the art of llaying railroadrails upon ties and has for' unyielding ,nature of the resulting vconstruce tion. Other objects will appear as the de scription'proceeds.

In carrying 'out the above-noted-object, a Itwo part housin is provided upon which the` rail rests an within which ayielding, non-metallic substance, such as rubber, 1 is placed. l, A. suitable means is provided for maintaining the rubber under compression` and the entireenclosing structure prevents extreme distortion Vand rapid disintegration of the rubber, especially wheresoft rubberl is used. More particularl the. present invention comprises lprovi ing.' a two part housing which has telescoping portions and inI this manner compression in the rubber is set up by-the telescoping of the respective housing portions.

Reference will panying drawin s fora more detailed descriptionof the evice, wherein: l

Figure 1' is. a plan view partly broken awa and partly in section o one'form of the invention.' v

Figure 2 is a section on the line 2?-2 of Figure 1 and looking in the direction of the arrows. Le. Figure 3 is aers ectiveof the telescoping portions use in igures 1 and 2.

Figure 4 is a section of a modiied form of the invention.

Figure 5 is a section of another formof f the invention.

Figure 6 is a section .of still another form of the invention. y Y

Figure 7 is a side elevation of the form of the invention shown in Figure 6. o A In the drawings a represents a metal tie upon which a rail b is carried. Between the rail andtie, a housing o is provided in which is confined a block of yielding non-metallic and cushioning material d. A suitable means. hereinafter described,l is provided for securing the rail ffv now be had to the accom-- taps causes the rail to ybe the tie and positioning the housing therebetween and this means may also `be adapted to place the confined block under compression.

1 In Figures 1, 2-'and 3 opposed telescoping y i housin 09 c2 areprovided and may be forme of j stampings Ahaving projecting edges of; o* which telescope with the co-operating housing ortions 1n assembling the de vice. The rai rests upon the bruising1 and the shocks .of the rail are cushioned through the-housing' and its cushioning element, i therail to the tie in a manner to setv 'up compression on. the housin yoke shaped clamps, e are provided an these yokesghave jaws whose engaging faces', converge inwardly along one jawasat eto conf fornito the slope of the top ofthe web'of the rail thegotherjaula?l having a face to engage :with the under sideof the'tie.

4 At eitherv side of the rail, apertures af land ai2 are'pr'ovided through' which the clamps i is -suiiciently oversize to permit a wedge to inserted therein. Drivin in thewe ge causes the clamps to more tightly y'thus secure the two in the manner desired.v

In Figure 4 the housing c is of a diierent size and shape. It merely consists of 'two telescoping portions o and c2 with a ,block of cushioning material disposed within. Holes d are formed in the housing, block and tie, and securing bolts e pass therethrough and serve to coniine, between their heads and nuts'e, dogs f. .The latter Ihave shoulders f set` up the. desired compression when the nuts e are taken u p on the bolts. The tie a has "apertures a 1n which'the ends of the dogsflie and tightening of the bolts and more irmly conpass and aperture a fined between the dogs.

The modified form shown'in e 5 is `similar to Fi re 4 eaceptv thatl oth the bolt and dog ie within the same hole, the

bolt head being T-shaped to engage the tie. In Fi es 6 and 7 the telescoping housing is of sti l a dienent shape. The upper portion is provided with a seat c for the rail and the lower ortion with. a depressed portion c2 which ies within an aperture a in the tie. Transversely through the housing and cushioning element d, extends boltc carrying yokes f which engage the rail and engage the railand tie andv which engage' the'rail and from one to the other tie and, when the nut e is taken Aup on, set up the desired degree of compression through the housing.

It `will be seen that in the foregoing description, structures have 'been set forth which. provide a means of ositively securing the rail to the tile and? provide a means for cushioning the shocks transmitted from the rail to the tie.

While several forms have been described above, it is understood that many other modifications may be emplo ed and the invention is not to be limited; except as delined by the appended claims.

What is clalmed is:

1. In a cushioning device between a rail and tie, a separate housing, a block of rubber completelyconfined lby the housingand means to exert a force transverse to the axis ofthe rail ,to secure the housing between the rail and tie.

2. In a cushioning device between a rail and tie, a housing comprising telescoping portions, a block `of rubber completely confined by the housing, and means to exert a force transverse to the axis of the rail 'to secure the rail to the tie with the housing therebetween and vary the degree of telescoping of the portions, whereby the shocks will be cushioned.

3. In a cushion device between a rail and tie, a housing comprising telescoping porv which further vand the securing of the rail by the housing, means to secure the rail to the tie with the housing therebetween, .a slot in the tie, and means associated with the slot. including the securing means, for setting up compression in the rubber, securingthe rail to the tie, and preventing the lateral displacement of the rail, all simultaneously.

5. In a cushion device between a rail and tie, a housing com rising telescoping ortions, a block of ru ber completely con ned by the housing, means to secure the rail to the tie with the housing therebetween, and a slot in the' tie, said Securing means including means to engage the slot to prevent lateral displacement of the rail, whereby such condition is effected 'simultaneously with the setting up of compression in the housing to the tie.

This s ecification signed this 20 day of July A. .1926.
